## Long description

The HPE Memory Module HPE DDR2 8GB 667MHz 2x4GB (MPN 397415-B21-RFB, EAN 882780082236) is a dual‑channel kit composed of two 4GB DDR2 fully buffered DIMM modules. Each 240‑pin module operates at 667 MHz (PC2‑5300) and uses a 1.5 V supply. Designed for HP Enterprise servers and compatible systems that accept 240‑pin DDR2 FB‑DIMMs, the kit provides 8 GB of ECC‑capable memory to improve data integrity and stability in server and workstation environments.
Advantages
This memory kit provides error‑checking (ECC) support and fully buffered DIMM architecture to enhance reliability in multi‑processor and high‑availability systems. The 667 MHz clock rate and matched dual modules enable consistent memory timing for balanced performance in memory‑intensive applications. The 240‑pin form factor and standard 1.5 V operating voltage ensure compatibility with systems specified for DDR2 PC2‑5300 FB‑DIMMs.
Suitable for
 Server upgrades in HP Enterprise systems that support DDR2 FB‑DIMMs
 Workstations requiring ECC memory for improved data integrity
 Environments running virtualization or database workloads with moderate memory demands
 Replacement of defective 4GB DDR2 FB‑DIMMs in matched pairs

How to use
Power down the server or workstation and disconnect power before installing the memory. Refer to the system service manual to locate compatible 240‑pin FB‑DIMM slots and the recommended slot population order. Align the module notch with the slot key and press firmly and evenly until the module latches into place. Install both 4 GB modules as a matched kit to ensure correct dual‑channel operation and ECC functionality. Reconnect power and verify memory is detected in BIOS or system management utilities before returning the system to operation.
Usage recommendations
Use this HPE DDR2 8GB 667MHz 2x4GB kit in systems that explicitly support DDR2 FB‑DIMMs and PC2‑5300 speeds. Maintain matched pairs and consult the server motherboard or vendor compatibility list to avoid mixing different memory types or voltages. For mission‑critical deployments, test new modules in a staging environment and enable ECC and memory diagnostics to monitor stability.
